Catch (But Don't Release) with Squid Web Proxying

We all know and love Squid, the versatile HTTP caching proxy. Squid conserves bandwidth, speeds up Web surfing, and comes with all kinds of controls to rein in unruly users: bandwidth throttling, domain filtering, and user access controls, to name a few. But no matter how skillfully you configure your Squid server, it's easy to bypass it. All your users have to do is delete the references to it in their Web browser configurations. If all you're doing with Squid is caching, this makes no sense, but then some folks just like to get away with stuff. If you're using Squid for filtering, bandwidth control or any other restrictions, you will certainly have a rebel underground to deal with.
